A system for inducing respiration according to one embodiment of the present invention comprises: an imaging unit for picking a respiration image of a patient; a respiration signal conversion unit for obtaining a respiration signal of the patient by image processing, and tracking and analyzing the respiration image of the patient obtained from the imaging unit; and a respiration determination unit for determining one or more of whether the obtained respiration signal is suitable for radiation treatment, whether the obtained respiration signal is stable, and whether a matching score between the respiration signal of the patient and a guide respiration is greater than a predetermined reference value; and a respiration guide unit for providing the respiration signal of the patient, obtained from the respiration signal conversion unit, together with a stored guide signal.

System and method for inducing respiration

A quality assurance system for radiation therapy equipment includes an image capturing unit installed on radiation therapy equipment and capturing an image of an indicating part indicating an operational state of the radiation therapy equipment, an image processing unit extracting an edge of the indicating part in image captured by the image capturing unit, a center point extraction unit extracting a center point with respect to the edge, and a quality evaluation unit evaluating quality of the radiation therapy equipment by tracking movement of the center point.

Quality assurance system for radiation therapy equipment, and quality assurance method thereof

A motion evaluation system includes a marker member including a body part having a first surface and a second surface parallel to the first surface, a reference indication part indicating a center of the first surface, and a plurality of markers arranged on the first surface to be spaced apart from the reference indication part. The marker member is arranged on an object such that the reference indication part is arranged at a reference point of a first coordinate system. A plurality of cameras generate coordinate images by respectively photographing the markers. A first coordinate calculator calculates first coordinate values of the markers in a first coordinate system by using separation distances of the markers and a first distance between the first surface and the second surface, the separation distances and the first distance being previously stored. A second coordinate calculator calculates second coordinate values of the markers in a second coordinate system by using the coordinate images generated by the cameras. A coordinate converter produces a conversion relationship between the first coordinate system and the second coordinate system by using the first coordinate values and the second coordinate values of the markers, and converts second motion information in the second coordinate system corresponding to a motion of the object objected by using the cameras to first motion information in the first coordinate system.

Motion evaluation system and method

A system for manufacturing a patient-specific applicator reconstructs a three-dimensional (3D) image by using a medical image of a patient, models an applicator structure for irradiating radiation onto a tumor tissue, based on a 3D image, generates printing data for 3D printing for manufacturing the patient-specific applicator based on the modeled applicator structure, and manufactures the patient-specific applicator based on the generated printing data.
